Huntsville (2009 population 18,280) is a town in the Muskoka Region of Ontario, Canada.

The community became an important industrial area in the late 19th century and had several saw, planing and shingle mills, as well as a tannery. Today, the many lakes and hills in the area, combined with the town's proximity to both Algonquin Park and Toronto, make Huntsville and the Muskoka region a major tourist destination.
